Intel Arc Graphics 2 Xe Mobile vs NVIDIA H800 SXM5 Comparison

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for the Intel Arc Graphics 2 Xe Mobile and the NVIDIA H800 SXM5. Neither GPU has recorded benchmark scores, and both sit at the 50th percentile among all GPUs in the database. The Intel part shows no wins and no losses against the H800, while the H800 likewise records zero wins and zero losses against the Intel part. As a result, direct performance comparisons must be drawn from the specification data rather than from measured frame rates or compute workloads.

The NVIDIA H800 SXM5 delivers a raw FP32 throughput of 59.30 TFLOPS, which is 46.3 times the 1,280.0 GFLOPS (or 1.28 TFLOPS) of the Intel Arc Graphics 2 Xe Mobile. In FP16 compute, the gap widens further: the H800 reaches 237.2 TFLOPS with a 4:1 ratio, while the Intel part manages 2.560 TFLOPS with a 2:1 ratio, a difference of roughly 92.7 times. Pixel rate favors the NVIDIA accelerator at 42.12 GPixel/s versus 20.00 GPixel/s for Intel, a 2.1x advantage. Texture rate shows the most extreme disparity, with the H800 at 926.6 GTexel/s compared to the Intel GPU's 40.00 GTexel/s, a 23.2x gap.

Memory bandwidth separates the two even more decisively. The H800 SXM5 features 80 GB of HBM3 on a 5120-bit bus, delivering 3.36 TB/s of bandwidth. The Intel Arc Graphics 2 Xe Mobile uses system shared memory with bandwidth marked as system dependent, meaning it has no dedicated VRAM allocation and no fixed bandwidth figure. The H800 also possesses 528 tensor cores and 16,896 shading units, while the Intel part has 256 shading units and no tensor core count listed. The Intel GPU does include 2 ray tracing cores, whereas the H800 lists no RT cores at all, making ray tracing the only category where the Intel part has a structural feature the NVIDIA accelerator lacks.

The H800's clock behavior differs substantially from the Intel GPU. NVIDIA runs a 1095 MHz base and 1755 MHz boost, while Intel starts at 300 MHz and boosts to 2500 MHz. Despite the higher top clock on Intel, the NVIDIA GPU's massive parallel width more than compensates in every throughput metric recorded.

Architecture Differences

The Intel Arc Graphics 2 Xe Mobile is built on the Xe3-LPG architecture, part of the Arc Graphics-M (Wildcat Lake) generation, using the Wildcat Lake chip. Its process node is 3 nm, fabricated by Intel. The NVIDIA H800 SXM5 uses the Hopper architecture with the GH100 chip, manufactured by TSMC at 5 nm. These represent two entirely different design philosophies: a low-power integrated GPU intended for portable devices versus a high-performance server accelerator.

The Intel part integrates 256 shading units, 16 texture mapping units, 8 raster operation units, and 2 ray tracing cores. The NVIDIA H800 SXM5 has 16,896 shading units, 528 texture mapping units, 24 ROPs, and 528 tensor cores, but lists no ray tracing cores. The transistor counts reflect the scale difference: the H800 contains 80,000 million transistors on an 814 mm² die, yielding a transistor density of 98.3 million per mm². Intel's transistor count and die size are listed as unknown, so no density comparison can be made.

Clock behavior differs by design intent. Intel runs a modest 300 MHz base clock that boosts to 2500 MHz, while NVIDIA runs a higher 1095 MHz base and a lower 1755 MHz boost. The Intel GPU's higher boost clock indicates a design tuned for bursty, latency-sensitive workloads in power-constrained environments. The H800's lower boost relative to its base suggests sustained throughput operation across a large parallel array.

Memory architecture separates the pair fundamentally. The Intel GPU uses system shared memory, meaning it draws from the host's main memory with no dedicated VRAM, no fixed bus width, and bandwidth that depends on the host platform. The H800 features 80 GB of dedicated HBM3 memory on a 5120-bit interface with a fixed 3.36 TB/s bandwidth. The H800's memory clock runs at 1313 MHz with 5.3 Gbps effective data rate.

API support also differs. The Intel GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA H800 SXM5 lists no DirectX, OpenGL, or Vulkan support, reflecting its server-oriented role where graphics APIs are not relevant. Display outputs follow the same pattern: the Intel part is portable device dependent, while the H800 has no display outputs at all.

Production status for both is Active. The Intel part released on 2026-04-15 and has a predecessor of HD Graphics-M. The H800 released on 2023-03-20, with a predecessor of Server Ada and a successor of Server Blackwell. The Intel GPU has no listed successor. The H800 uses a PCIe 5.0 x16 bus interface, while the Intel GPU is an IGP with no separate bus interface. Slot width differs: the Intel part is an IGP, the H800 is an SXM Module.

Where Each One Wins

The NVIDIA H800 SXM5 wins decisively in every raw compute category recorded. Its FP32 throughput of 59.30 TFLOPS dwarfs the Intel part's 1,280.0 GFLOPS. Its FP16 output of 237.2 TFLOPS exceeds Intel's 2.560 TFLOPS by an order of magnitude measured in the dozens. Texture rate of 926.6 GTexel/s versus 40.00 GTexel/s indicates the H800 is built for texture-heavy and compute-bound server workloads. Pixel rate of 42.12 GPixel/s versus 20.00 GPixel/s gives it a 2.1x edge in fill-rate-bound tasks. The 3.36 TB/s memory bandwidth, backed by 80 GB of HBM3, enables data movement at a scale the Intel part cannot approach with system shared memory.

The Intel Arc Graphics 2 Xe Mobile wins in power efficiency and integration. Its 25 W TDP is 28 times lower than the H800's 700 W. It requires no power connectors, while the H800 demands an 8-pin EPS. The Intel GPU is an IGP, eliminating the need for a separate card slot or external power delivery. Its 2500 MHz boost clock is higher than the H800's 1755 MHz, indicating faster per-clock execution on light workloads. It also provides display outputs (portable device dependent) and full graphics API support with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, none of which the H800 offers. The 2 ray tracing cores give it a feature the H800 lacks entirely.

For portable devices, the Intel GPU is the only viable option: it operates within a 25 W envelope, uses shared system memory, and outputs to a portable device's display. The H800 cannot function in such a role, as it has no display outputs and consumes 700 W. For server compute, the H800 is the clear choice: its 16,896 shading units, 528 tensor cores, and 3.36 TB/s bandwidth target exactly the workloads servers run. The Intel part's 256 shading units and system shared memory cannot sustain the data throughput required for large-scale training or inference.

The Verdict

The data indicates a complete separation of use cases. The NVIDIA H800 SXM5 is a server accelerator with no display outputs, no graphics API support, and a 700 W power draw. The Intel Arc Graphics 2 Xe Mobile is an integrated GPU for portable devices with a 25 W TDP, shared system memory, and full graphics API compatibility. Anyone needing FP32 compute beyond 1.28 TFLOPS, FP16 throughput above 2.560 TFLOPS, or memory bandwidth above what system shared memory provides should select the H800. Anyone operating within a 25 W power envelope, requiring display output, or running DirectX 12 Ultimate, OpenGL, or Vulkan workloads must choose the Intel GPU, as the H800 supports none of those features.

The release dates reinforce this split: the H800 launched in March 2023 for the server market, while the Intel part launches in April 2026 for mobile integration. The H800's predecessor and successor are both server products, confirming its dedicated role. The Intel part's predecessor is HD Graphics-M, a mobile integrated graphics line. Both GPUs remain in active production, but they address mutually exclusive market segments. The verdict is straightforward: the H800 dominates all recorded compute metrics and is the appropriate choice for server workloads, while the Intel GPU is the appropriate choice for portable graphics where power, integration, and API support matter more than raw throughput.
